NM: Users getting migrated with errors, Error: NSFFolderGetIDTable returned 'Attempt to perform f (4298075)

Issue

What does this error mean from the migration log?

Error: NSFFolderGetIDTable returned 'Attempt to perform folder operation on non-folder note.' getting note table
Error: Error getting note table for skipped folder: %s

Solution

This usually means there is a corrupt note in the Notes database.
What you can do with this user's mail file is to run compact -c on the server console for this users mail file.
Running a copy style compaction will rebuild the design list so I am wondering if something is wrong the design list in this database.
Or pull a new replica of the mail file which will get the tables and notes id back in consecutive order and then migrate that new replica.

To remove the migrated mail and start over, go to the Advanced migration view, select the user, and click "Clear or Reset users - Remove migrated data" view action button.
Then confirm the migrated data has been removed from the user's Exchange mail
Clear the user history; click "Clear or Reset users - Clear user history"
Reset the user
Run the migration
